SPRAYING APPARATUS.

Specification of Letters Patent.

I Application filed September 9, 1914. seria no; se0,s77.

T all whom it may concern Be it known that I, \VILLIAM P. CAsHnN,

. a citizen of the United States, residing at liquid Lincoln, in the county of Logan and State of Illinois, have invented aSpraying Apparatus, of which the following is a specification.

The primary object of my invention is to provide a spraying apparatus especially adapted for use in coal mines, by which a liquid preparation, as lime-water, may be sprayed in the tunnels of the mine to allay dust and thereby not only purify the air but minimize the danger of explosions and fire; the discharge of the several spraying nozzles being such as to thoroughlycleanse the air of combustible material as well as cover the side walls and top with a preservative which will render the woodwork in the tunnel noncombustible,

A further object of my invention is to provide an apparatus of this character which may be run on the tracks used by the coal cars in conveying the coal to the shaft, and

which may tle expense. I

Other objects and advantages of my invention will hereinafter appear, and what I claim as new, and desire to secure by Letters- Patent, is more specifically set forth in the appended claims.

be operated at comparatively lit- In the accompanying drawings, which form a part of this specification: Figure .1 is a side elevation, illustrating a spraying apparatus constructed in accordance with my invention. ,Fig. 2 is an end viewv thereof. Fig. 3 is a top plan view. Fig. 4 is a detail sectional view, on a linedirectly in the rear ofthe airepumps, to more clearly show said air-pumps and connections. Fig. 5 is a-detail view of the supporting frame .for the air-pumps and operating mechanism thereof. F ig. 6 is adetail view showing a modification. I e

.Like numerals of reference indicate, like parts in all the figures of the drawings In carrying out my invention I provide a large. closed tank 6, preferablymade-of' boiler iron and cylindrical in shape, with the heads 7, 7, securely rivetedto the body, as customary in tanks of this general character. In the present instance the tank is mounted on a suitable wheeled truck, comprising longitudinal beams or sleepers 8, 8,,

resting on the axles 9,9, of the track-Wheels Patented Nov; 9; 11915;]

10, said beams or sleepers being connected near their ends by. iron bars 11, 11,.and 12,1

12, arranged in pairs the ends of the bars of each pair embracing the upperand lower edges of the beams, to which they are bolted,

and the upper bar curved downwardly be; tween the beams corresponding with the.

curve of the cylindricaljtank so that the latter may seatsecurely on the truck. The truck is provided with a suitable coupling or draw-bar 13, at its ends, for connecting the same to acoal-car or other means for V pulling it along the tracklaid in the tunnel for the coal cars to run upon. e V The tank 6 is securely held upon the truck by means of iron bands or straps l4, 14, se-

cured at theirlower endsto :the beams 8,, and 'connected'at the upperside of said tank.

by clamping-bolts l5, and .to these iron bands or straps the frame for supporting the airpump and its operating mechanism is attached, as hereinafter described. l

The tank 6 is intended to contain any liquid preparation or solution suitable for. allaying and preserving combustible dust such as usually'collectsin coal mines and saturating Wood-work to make it fire-proof,

I and for the purpose of spraying this liquid in the most effectivemanner there is located. at the lower end of one of the heads v7 an outlet pipe 16, having a valve 17', andconnecting with a plurality of discharge pipes 18 terminating in nozzles 19 of any ap proved patterns In the present instance there are three dischargepipes, one disposed vertically so that the nozzle throw a spray upwardly and upon the coil? ing or top of the tunnel, and opposite laterally disposed discharge pipes the nozzles of which spray in opposite directionsgtoward the sides and portions, of the bottom of the tunnel. In this manner, as will be readily I seen, the entire air space of thetunnel will besprayed or thoroughly washed and suiii cientoftheliquid preparation or solution deposited, on the Wood-work of the tunnelto .90 7 thereof will.

preserve it'yand prevent it fromcatching 1 fire.

the tank out of the discharge nozzles with In order to force-the liquid. contents of suflicient force" to provide the necessary, spray I provide alnpressure in said tank by: means of a pair of air-pumps 20, 20Iarranged on a line with each other and having their piston-rods 21 connected tor a wrist;

wheel 21 on one end of a drivingshaft 22, the latter being driven from one of the track-wheels 10 by a sprocket chain 23 passing over sprocket-wheels 24: and 25, connected to said shaft and sprocket-wheel, respectively. The sprocket-wheel 2a is loose on the shaft and has a clutch-member 26 for slidable engagement with a companion clutch-member 27 fixed to the shaft, and this clutch is thrown in and out of engagement by means of a lever 28, supported in the manner hereinafter described.

The air-pumps discharge into pipes 20, 20 respectively, which are connected to a pipe 29, extending into the tank, and through which the air under pressure from the pumps is led to the tank; a predeterminedmaximum air-pressure in said tank being maintained by the-employment of a safety-valve 30, of any approved pattern.

The air-pumps and driving shaft are carried by aniron yoke 31, mounted on a supporting-frame at one side of the upper part of the tank and secured to the holding straps 14. This supporting frame consists of an iron-plate 32, a V-shaped fiat bar 33, bolted at its ends to the end portions of said plate, and a V-shaped fiat bar 3%, bolted at its angle portion to the angle portion of the aforesaid bar by the bolts, as'35, which secure the supporting-yoke 31 to the supporting-frame, said yoke being supported in proper horizontal alinement above the frame by interposed sleeves 36. The supportingframe is braced by a V-shape bar 37, bolted to the frame bars 33 and s4, and said bar 37 serves also as afulcrum for the lever 23, hereinbefore referred to. Additional bracebars, 38, connect the frame bars, as shown in the-drawing, and one of these bracebars is provided with recesses, as 33 and 38 with which the operating-lever 28 engages for holding the clutch in or out of operative engagement, according to the position of the lever, as will be understood. The ends of the plate 32 and frame-bar 3e are apertured, as at 32" and 34:, respectively, to receive the ends of the bolts 39 and 4:0 projecting from the tank orholding-straps 14;, and upon which nuts 41 are threaded for attaching the frame to said tank. In this manner, as will bereadily seen, the holding straps, frame, and partscarried thereby, may be conveniently removed from the tank, thus permitting the parts mentioned to be applied to any tank in the form of an attachment.

It will be noted that the handle of the.

lever for operating the clutch is located beyond the opposite end of the tank from the spraying-nozzles, so that the operator may be out of the way of the spraying liquid, and in order that the spraying of the liquid may be regulated, or cut off by the operator convenientlyjat anytime, the valve or cut-0E 17 is provided with'a rod 42, supported by a bracket-arm 43 projecting from the tank, the rod 42 having a crank 44: to which is attached a pulling-rode5 terminating in its outer end in a loop or handle &6 by which it is manipulated, said loop or handle being located adjacent the operating end of the lever 28. The outer end of this pulling-rod is supported by a link 47, attached to and extending froma part of the apparatus for the purpose.

In the modification Fig. 6 a transmitting gear is interposed between the driving-shaft 22 and wrist-wheel 21, and in this instance a sprocket-wheel 50 is mounted on the inner end of shaft 22 and connected by chain-belt 51 to a sprocket-wheel 52 on an auxiliary.

shaft53, the latter being connected to drive i the wrist-wheel by sprocket-wheel 54, chainbelt 55 and sprocket-wheel 56, the latter being fixed on a stub-shaft 57 carrying said wrist-wheel.

Having fully described the constructionof my improved spraying apparatus, the operation. of the same will be readily understood from the accompanying drawings, for in practice the truck carrying the tank with its spraying nozzles and air-pumps, will be attached to a coal-car so as to be drawn through the mine thereby, or it may be drawn independently if desired, and asthe truck-wheel 10 carrying the sprocket-wheel is revolved by theinovement of the truck the chain 23 will turn the sprocket-wheel 24,

and the engaging clutch connecting said sprocket-wheel with the driving-shaft22 will turn the latter thus operating the airpnmps 20, 20, to produce the required airpressure in the tank, which will force the liquid contents out of the nozzles in a plurality of sprays reaching all parts of the mine or tunnel as the apparatus passes therethrough. The air-pressure in the tank is limited by the safety-valve, and the spraying of the liquid regulated by operating the cut-off valve through theintervention of the pulling-rod 45. In transporting the apparatus from place to place, or at any other 1 time, the spraying may be cut 05 by operating the valve 17, and the air-pumps thrown out of operation by-operati'ng the lever 28 to disengage the clutch.

The nozzles employed may be, and preferably are, Ofthe adjustable'type, permittingthe volume or character of the spray tobe changed by turning the cap, and inpractice I prefer that the nozzles at the ends of the lateral discharge pipes be connected thereto by universalfiioints 48, so that said nozzles may be turned and change the direction of the spray, according to the size of the tunnel or mine.

Though I have described. my invention or spraying apparatus as used for the purpose of spraying mines, it will be understood, of

course, that it may be used for the purpose of spraying trees, shrubbery, &c., and in this instance ordinary ground-wheels would be applied to the truck in place of track-wheels. Having described my invention, I claim: 1. In a spraying apparatus for the purposes set forth, the combination with a wheeled truck, of a tank mounted horizontally thereon, and discharge nozzles at the lower part of the tank for spraying the contents thereof; together with holding straps secured to the truck and embracing the tank, a supporting-frame bolted to the straps, airpumps mounted on the supporting-frame and connected to the tank for forcing air into the same, and means for operating the air-pumps from the Wheels of the truck, substantially as shown and described.
